LEON CARRIGABURU, OF HAVANA, CUBA.

IMPROVEMENT IN STEAM-PUMPS.

Specification-forming part of Letters Patent No. 59,519, dated November 6, 1866.

To all whom it may concern:

Be it known that I, LEoN GAERIGABURU, of Havana, Island of Cuba, have invented a new and Improved Steam Engine and Pump; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the sa me, reference being had to tlie accompanying drawings, forming part of this specification.

The nature of tliisinveii tion consists in working the slide-valve of a steam engine and pump directly by the piston of the main cylinder', thus dispensing with the use of cam or eccentric and their attachments generally used for working the slide-valve.

It more particularly consists in the arrangement of the valves inside of the cylinder, one at each end, and attached to a rod that rims longitudinally from end to end of both cyliiiders, and passing through proper stuffingboxes located at the end ofeach cylinder toward each other. The pistons are also attached in the same manner to the rods as the valves.

To enable others skilled in the art to make and use my invention, I will proceed to de scribe its construct-ion and operation.

Figure l is a longitudinal vertical sectional elevation from the line x m. Fig. 2 is an end elevation of the saine.

Letters of like name and kind refer to like parts in each of the figures.

A represents the `base or foundation upon which the cylindersv of my improved steamengiiies stand, and to which they are firmly secured by the feet B.

O C are the cylinders, made in the ordinary manner, with steam-chests D D, located upon the exterior surfaces ofthe said cylinders.

Upon the outside of the cylinder C C are attached small valve-cylinders, E E', in which are fitted and Work slide-valves F F', one at each end of the said cylinders E E. These cylinders are each provided with ports or openings, one at each end, that communicate with the inside of the cylinders O G', and through which the steam passes from the steam-chests into the cylinders O C and drives the pistons Gr G. These pistons G G are located and secured upon the ends of the piston-rod H, which passes through stuffing-boxes I I into the cylinders O C.

J is the slide-valve rod that passes through stuffing-boxes K K, and upon which are securedI the valves F F. These valves are located upon the said valve-rod in such a inanner as to bring them against the ports, so as to open and close them as the piston moves back and forth.

L is the induction or steam pipe through which the steam passes into the cylinder.

O is the eduction or exhaust pipe from which the exhaust-steam escapes after having` been used.

P represents the `cyliiider-heads, made and secured to the cylinder in the common way.

It may here be observed that openings may be made in the toe of the valve above the diameter ofthe cylinder for the induction of steam, but is not shown in the drawings.

The operation of my improved engine and pump is simple and effective, and is put in motion by admitting' the steam into the cylinder() from the steaiii-chestD through the opening Q, which drives the piston in the direction of the arrow until it strikes the toe f of the valve F and causes it to move along` to the end of the cylinder, and closes the valve at the opposite end from the direction of the arrow, and opens the valve at the end where the piston is, and thus a steady reciprocating motion is kept up.

This may be used either for a Water or steam engine. y

Having thus described myinvention, I claim as new and desire to secure byLetters Patent- The valves F or F', furnished with toes or projections extending through the ports of the cylinder, so as to cause the valves to be actuated by the piston, substantially as described.
